In seeking wisdom thou art wise; in imagining that thou hast attained it - thou art a fool.

Ridicule is the best test of truth.

Know the true value of time; snatch, seize, and enjoy every moment of it. No idleness, no laziness, no procrastination: never put off till tomorrow what you can do today.

There is time enough for everything in the course of the day if you do but one thing once; but there is not time enough in the year if you will do two things at a time.

I recommend you to take care of the minutes, for the hours will take care of themselves.
